Ok, now there is more information for a meaningful response.
Your current situation
1) There are no automatic carwash facilities in your market/region (country?)
2) There are no equipment distributors or technicians in your market/region
3) You will not be hands-on with respect to customer service, management, maintenance or repairs
4) You intend to build a wash and then pay unskilled laborers to operate it and take care of the business for you, none of which have any experience with automatic carwash systems
5) You have no experience in the carwash industry
6) You intend to serve a market where the customer is use to hand-wash quality
My assessment is that you have a slippery slope to climb. If you intend to borrow money for this project, I believe you would have a zero probability of obtaining a loan given your current situation.
I would agree with the other gentleman and suggest that you contact the closest European equipment manufacturer and have one of their distributors "hand-hold" you through the process of learning about the carwash industry and the many facets that are involved in the planning, development and operation of an automatic carwash system. Otherwise, I believe you will become very frustrated or you will make a mistake(s) that will cost you $100,000's.
